Supports must be placed under thepanel on both sides, near the line of cut andnear the edge of the panel.5) Do not use dull or damaged blades.Unsharpened or improperly set blades pro-duce narrow kerf causing excessive friction,blade binding and kickback.6) Blade depth and bevel adjusting lockinglevers must be tight and secure beforemaking cut.If blade adjustment shifts while cutting, it maycause binding and kickback.7) Use extra caution when making a “plungecut” into existing walls or other blindareas.The protruding blade may cut objects thatcan cause kickback.V. SAFETY INSTRUCTIONSFOR THIS SAW1) Check lower guard for proper closingbefore each use. Do not operate the sawif lower guard does not move freely andclose instantly. Never clamp or tie the lowerguard into the open position.If saw is accidentally dropped, lower guardmay be bent. Raise the lower guard with theretracting handle and make sure it movesfreely and does not touch the blade or anyother part, in all angles and depths of cut.2) Check the operation of the lower guardspring. If the guard and the spring are notoperating properly, they must be servicedbefore use.Lower guard may operate sluggishly due todamaged parts, gummy deposits, or a build-up of debris.3) Lower guard should be retracted manual-ly only for special cuts such as “plungecuts” and “compound cuts.” Raise lowerguard by retracting handle and as soonas blade enters the material, the lowerguard must be released.For all other sawing, the lower guard shouldoperate automatically.4) Always observe that the lower guard iscovering the blade before placing sawdown on bench or floor.An unprotected, coasting blade will causethe saw to walk backwards, cutting whateveris in its path.
